What happens during anaphase I and anaphase II stage?One of the two cell divisions is meiosis. From a single parent cell, it generates four daughter cells. Each cell has half of the parent cell's chromosomes. Meiosis I and Meiosis II are the two primary mechanisms that cause meiosis. Four subdivisions make up each meiosis. In meiosis I, anaphase I takes place, and in meiosis II, anaphase II. The homologous chromosomes are pulled apart and moved to the opposite ends of the cell during anaphase I, whereas during anaphase II, the sister chromatids of each chromosome are separated and moved towards the poles. Additionally, anaphase I happens when a cell is in the diploid condition, but anaphase II happens when a cell is in haploid condition.
The cell has 12 chromosomes, after anaphase I stage each chromatid is considered a separate chromosome structure, hence there will be 24 chromosomes. After meiosis I is complete the number of chromosomes again become 12 because of the division of the nucleus.
At anaphase II, the sister chromatids are separated hence, the number of chromosomes remain 12.

The receptors for steroid hormones are located inside the cell instead of the membrane surface like most other signal receptors. How do steroids gain access to their receptors
The steroids gain access to their receptors because steroid hormones are lipid soluble and can readily diffuse through the lipid bilayer of the cell membrane.
The steroid hormone dissociates from its plasma carrier protein and diffuses throughout the mobile membrane. After gaining entry to the mobile, the free hormone binds to an intracellular receptor and alters gene transcription.
In keeping with the free hormone speculation, due to their hydrophobicity, steroids are able to freely diffuse across lipid bilayers; but, megalin-established endocytosis has been proven to be at the least partly answerable for the uptake of sex hormones and nutrition D.
Steroid hormones, in general, are believed to freely diffuse across a membrane partly due to their close resemblance to ldl cholesterol, but recent evidence indicates that they could additionally enter cells thru receptor-mediated endocytosis.

The number of possible chromosome orientations in a cell containing 4 pairs of chromosomes are: 16.
The formula to calculate the possible orientations of chromosomes is 2ⁿ. Here, n stands for the number of chromosome pairs. From the question we know that the chromosome pairs are 4 in number and hence 2⁴ = 16.
Chromosomes are the carriers of genetic information and are crucial for the inheritance of traits from one generation to the next. They are long, thread-like structures made of DNA (deoxyribonucleic acid) and proteins. They are found inside the nucleus of eukaryotic cells, which are cells that have a defined nucleus enclosed within a membrane.

A rock resting high on a cliff is an example of an object with
what type of energy? (2 points)
Kinetic energy because it is doing work
O Kinetic energy because it has the ability to do work
Potential energy because it is doing work
Potential energy because it has the ability to do work?
Answer:
Potential energy because it has the ability to do work
Explanation:
Kinetic energy is when an object is doing work, and potential energy is when an object has the potential to get kinetic energy either due to it's position or molecular composition. In this case since the rock is resting high on a cliff, it has a bunch of potential energy, due to it's position, because gravity. If it were to fall of the cliff, it would then convert that potential energy to kinetic energy, but at that moment, since it's resting, it's only potential energy, because it has the potential to convert into kinetic energy. So the correct answer is: Potential energy because it has the ability to do work

The diversification of reptiles facilitated by the evolution of the reptilian egg is a good example of adaptive radiation.
What is adaptive radiation?
A rapid growth in the number of species sharing a common ancestor that is characterized by high ecological and morphological variation is known as adaptive radiation. It is fueled by organisms' ability to adapt to novel ecological situations.
The formation of their scaly skin, which contains the protein keratin and waxy lipids, limiting water loss from the skin, was one of the major adaptations that allowed reptiles to live on land. Because of this occlusive skin, reptiles and amphibians both use their lungs to breathe rather than their skin for respiration. The phenomenon of adaptive radiation was first observed by Darwin. During the Mesozoic era, the age of reptiles ( dinosaurs), mammals were small, generalized, and rare.
